InfoWorld's Serdar Yegulalp provides a look at the best apps for boosting the battery life of your Android device. "The best place to start if you just want to survey your power usage habits is Battery Indicator. To follow that up with actual power management, Green Power and JuiceDefender are your best bets. 2x Battery is not a bad program, but it's limited to managing cell data and not Wi-Fi connections. If that feature were added in a future revision, 2x Battery would be a real contender."
